Possibly, depends on the location in the game. With this config, lowest settings, lowest FOV, and FSR3 set to Quality, you can hit 60 FPS in some scenarios. FSR3 is supposed to double your framerate but I think with the overhead it’s more like increasing your FPS by 25% on Steam Deck, so you should be able to reach 90 on the OLED.
